Ball & Ring Gravesande's - Chain Type L1-Art & Craft-L2-Ceramics & Modelling Reinforces comprehension across multiple episodesThe Ball and Ring Gravesande's Apparatus (Chain Type) is a classic physics demonstration tool designed to show the expansion and contraction of metals with heat. At room temperature, the brass ball easily passes through the metal ring. Once the ball is heated, it expands and can no longer pass through the ring, visually demonstrating the principle of thermal expansion. This apparatus includes a brass ball and ring, both mounted on sturdy steel rods
